At least six people have been killed and more than 30 injured in a blast outside a mosque in northwest Pakistan.
The explosion happened in the city of Parachinar, a mainly Shia Muslim area on the Afghan border.
Reports say a car packed with explosives was left near the women’s entrance of the mosque as people gathered for Friday prayers.
The Pakistani Army has sent a helicopter to help take the injured to hospital.
A surgeon told AFP news agency he expected the death toll to rise.
Parachinar is the capital of the Kurram, one of Pakistan’s seven tribal districts.
These areas are governed according to local laws and customs and are known for sectarian clashes between Sunni and Shia Muslim groups.
In January a bomb blast in the vegetable market in Parachinar killed at least 20 people.
A faction of the Pakistani Taliban (TTP) said it was behind the blast.
